We follow a teenage boy, whose mother and surgeon father are visiting another Argentine family on the rugged south Uruguayan coast. It is the relationship between the boy and his hermaphrodite teen host that we follow, each, in their own ways, confused and anxious adolescents uncertain of their roles in life and their futures. This sensitive and observant film is anchored by Ricardo Darín as the young 'girl's' marine biologist father and his attempts to give her/him the freedom to find his/her own way. Superb.
